Comment (by mdavis):

 To clarify, this is not an issue with `ST_Intersection`.  The issue is
 that GEOS is incorrectly reporting a MultiPolygon with nested shells as
 valid.  `ST_Intersection` is failing as expected when used on invalid
 geometry.

 The GEOS IsValid issue is due to a bug.  This is now fixed.
